利用空调机冷凝热与辅助热源制备卫生热水的技术与工艺 The Technology and Process of Making Sanitary Hot Water Using the Condensation Heat of Air Conditioner and Auxiliary Heat Source

所属技术领域Technical field

本发明涉及一种利用空调机冷凝热与辅助热源制备卫生热水的技术与工艺,属于节能技术领域;主要针对大型宾馆、医院等有卫生热水需求的公共建筑的中央空调系统的冷凝热回收和利用,用于制备卫生热水。The invention relates to a technology and process for preparing sanitary hot water by utilizing the condensation heat of an air conditioner and an auxiliary heat source, which belongs to the field of energy-saving technology; it is mainly aimed at the recovery of condensation heat of central air-conditioning systems in large hotels, hospitals and other public buildings that require sanitary hot water And use, for the preparation of sanitary hot water.

背景技术Background technique

目前,空调机组的冷凝热回收技术主要有两种:一种采用在压缩机与冷凝器之间串联一热回收换热器,自来水进入热回收换热器吸收压缩机出口高温冷剂蒸气的显热,然后进入辅助热源或作为热泵机组的低温热源制备卫生热水,实现冷凝热的部分回收;一种采用省却冷却塔,以空调制冷机组的全部冷却水作为热泵机组的低温热源制备卫生热水,实现冷凝热的全部回收。在实际工程中,前者由于在压缩机与冷凝器之间串联热回收换热器,导致压缩机的结构复杂,冷剂管道的阻力损失增加,严重影响空调机组运行的稳定性和运行效率。后者难以实现冷凝热的回收量和热水负荷的匹配,并且由于省却冷却塔,不能保证空调系统的运行效率和稳定性。由于以上两种空调机组冷凝热回收技术的局限性,所以其在实际工程中难以大规模的推广和应用。绝大多数空调机组的冷凝热通过冷却塔与环境进行热交换散失到环境中,造成能源的浪费和环境的污染。At present, there are two main condensation heat recovery technologies for air-conditioning units: one uses a heat recovery heat exchanger connected in series between the compressor and the condenser, and tap water enters the heat recovery heat exchanger to absorb the apparent high-temperature refrigerant vapor at the outlet of the compressor. Then enter the auxiliary heat source or use it as the low-temperature heat source of the heat pump unit to prepare sanitary hot water to realize partial recovery of condensation heat; one uses the cooling tower and uses all the cooling water of the air-conditioning refrigeration unit as the low-temperature heat source of the heat pump unit to prepare sanitary hot water , to achieve full recovery of condensation heat. In actual engineering, due to the heat recovery heat exchanger connected in series between the compressor and the condenser in the former, the structure of the compressor is complicated, and the resistance loss of the refrigerant pipeline increases, which seriously affects the stability and efficiency of the air conditioning unit. The latter is difficult to achieve the matching of the recovery of condensation heat and the hot water load, and because the cooling tower is omitted, the operating efficiency and stability of the air conditioning system cannot be guaranteed. Due to the limitations of the above two condensation heat recovery technologies of air-conditioning units, it is difficult to promote and apply them on a large scale in actual projects. The condensation heat of most air-conditioning units is lost to the environment through the heat exchange between the cooling tower and the environment, resulting in energy waste and environmental pollution.

发明内容Contents of the invention

为了克服现有冷凝热回收技术所引起的空调机组运行效率低、稳定性差以及冷凝热的回收量和热水负荷的不匹配等问题,本发明提出了一种利用空调机冷凝热与辅助热源制备卫生热水的技术与工艺,提高了空调机组的运行效率、增强了空调机组的稳定性;实现了空调机组冷凝热的部分或全部回收和冷凝热回收量同热水负荷的匹配。In order to overcome the problems of low operating efficiency and poor stability of the air-conditioning unit caused by the existing condensation heat recovery technology, as well as the mismatch between the recovery of condensation heat and the hot water load, the present invention proposes a method of using the condensation heat of the air conditioner and auxiliary heat source to prepare The technology and process of sanitary hot water improves the operating efficiency and stability of the air-conditioning unit; realizes the partial or complete recovery of the condensation heat of the air-conditioning unit and the matching of the recovery of condensation heat with the hot water load.

本发明解决其技术问题所采用的技术方案是:在空调机组的冷凝器处并联一辅助加热与蓄热水箱系统。该系统由辅助热源、蓄热水箱等与自动控制系统并联组成。自动控制系统由冷却水温度控制系统,冷却水补水控制系统,热水温度控制系统并联组成。冷却水温度控制系统由温度传感器、温度控制器和电动三通阀串联组成;冷却水补水控制系统由流量传感器、流量控制器和补水电动阀串联组成;热水温度控制系统由温度传感器、温度控制器和电磁阀串联组成。冷却水温度控制系统的控制策略:当冷却水温度大于45℃时,温度传感器控制温度控制器使电动三通阀动作,空调系统的冷却水直接进入蓄热水箱,供用户使用;当冷却水温度小于45℃时温度传感器控制温度控制器使电动三通阀动作,空调系统的冷却水直接进入辅助热源,经加热后达到50℃左右,然后进入蓄热水箱,供用户使用。冷却水补水控制系统的控制策略:通过安装在辅助加热与蓄热水箱系统的冷却水入口处的流量传感器控制流量控制器使补水电动阀动作,调整补水电动阀的开度,调节冷却水的补水量。热水温度控制系统的控制策略:通过安装在蓄热水箱处的温度传感器控制温度控制器使电磁阀动作,当供水管处的水温低于40℃时,电磁阀开启,循环水泵启动,将热水打入辅助热源进行再加热,以满足用户的要求。在夏季,空调机组的冷却水(一般为40℃左右)分为两路。一路进入辅助加热与蓄热水箱系统,制备卫生热水;另一路进入冷却塔,经冷却后循环使用。冬季和过度季,通过辅助热源加热自来水,制备卫生热水。从而达到提高了空调机组的运行效率、增强了空调机组的稳定性,实现空调机组冷凝热的部分或全部回收以及冷凝热回收量同热水负荷的匹配。The technical scheme adopted by the present invention to solve the technical problem is: an auxiliary heating and heat storage tank system is connected in parallel at the condenser of the air-conditioning unit.

The cooling water temperature control system consists of a temperature sensor, a temperature controller and an electric three-way valve in series; the cooling water replenishment control system consists of a flow sensor, a flow controller and a water replenishment electric valve in series; the hot water temperature control system consists of a temperature sensor, a temperature The device and the solenoid valve are connected in series. The control strategy of the cooling water temperature control system: when the cooling water temperature is higher than 45°C, the temperature sensor controls the temperature controller to make the electric three-way valve act, and the cooling water of the air conditioning system directly enters the heat storage tank for the user; when the cooling water When the temperature is lower than 45°C, the temperature sensor controls the temperature controller to activate the electric three-way valve, and the cooling water of the air conditioning system directly enters the auxiliary heat source, reaches about 50°C after heating, and then enters the hot water storage tank for users. The control strategy of the cooling water replenishment control system: through the flow sensor installed at the cooling water inlet of the auxiliary heating and hot water storage tank system, the flow controller is controlled to make the water replenishment electric valve act, adjust the opening degree of the water replenishment electric valve, and adjust the flow rate of the cooling water. Hydration volume. The control strategy of the hot water temperature control system: the temperature sensor installed at the hot water storage tank is used to control the temperature controller to activate the solenoid valve. When the water temperature at the water supply pipe is lower than 40°C, the solenoid valve is opened and the circulating water pump is started. The hot water enters the auxiliary heat source for reheating to meet the user's requirements. In summer, the cooling water (generally around 40°C) of the air conditioning unit is divided into two paths. One way enters the auxiliary heating and hot water storage tank system to prepare sanitary hot water; the other way enters the cooling tower for recycling after cooling. In winter and transitional seasons, the tap water is heated by an auxiliary heat source to prepare sanitary hot water. In this way, the operating efficiency of the air conditioning unit is improved, the stability of the air conditioning unit is enhanced, partial or complete recovery of the condensation heat of the air conditioning unit is realized, and the matching of the recovered condensation heat with the hot water load is realized.
